When should I use Mockito?
Mockito is used to test the functionalities of the classes without depend up on the database connection or properties file read or file server read to test a functionality. Mock objects do the mocking of the real service. A mock object returns a dummy data corresponding to some dummy input passed to it.
What is the advantage of Mockito?
Benefits of Mockito. No Handwriting − No need to write mock objects on your own. Refactoring Safe − Renaming interface method names or reordering parameters will not break the test code as Mocks are created at runtime. Return value support − Supports return values.
Why do we need Mockito in JUnit?
Mockito is a library that enables writing tests using the mocking approach. JUnit is used to test API’s in source code. To test API’s in JUnit, sometimes we may require data classes. To create those, we can use mockito.
How does Mockito work in Java?
With Mockito, you create a mock, tell Mockito what to do when specific methods are called on it, and then use the mock instance in your test instead of the real thing. After the test, you can query the mock to see what specific methods were called or check the side effects in the form of changed state.

What is JMock in Java?

The jMock library: lets you precisely specify the interactions between your objects, reducing the brittleness of your tests.
What is Mockito Python?
python-mockito – a modern replacement for Python mock & patch. The library I want to introduce to you – python-mockito – is a port of Java’s testing framework with the same name. It’s safe by default unlike mock from the standard library. python-mockito has a nice, easy to use API.

What is Mockito spy?
A Mockito spy is a partial mock. We can mock a part of the object by stubbing few methods, while real method invocations will be used for the other. By saying so, we can conclude that calling a method on a spy will invoke the actual method, unless we explicitly stub the method, and therefore the term partial mock.

What is the use of mockmockito?
Mockito facilitates creating mock objects seamlessly. It uses Java Reflection in order to create mock objects for a given interface. Mock objects are nothing but proxy for actual implementations. Consider a case of Stock Service which returns the price details of a stock.
